It iscustomary to provide the blank ffromtwhich `the body Twallfofi thelcontainer is formed with a projecting tongue invalignment with thescored `portion which i-s to form the tearing strip so that a key may beplaced on the tongefand by the turning ofthe key theftaring strip`removed and `thusthe container pcoarrecl.`

o An object of the present invention is to provide a container having atearing strip 'which is'tongueless; that is, the body wall is scoi'edsothat the end of the tearing strip( to which the key isotobe applied is apart otthe bodywall of the container` and `not a `projecting portion ofthe body blank. o o

A further object of the invention is to provide a -oontainer of theabove type with an inserted collar which is so shaped in the region ofthe tearing strip to permit the insertion of a tool through a formedopening in the body wall for breaking the body wall at the end of thetearing strip.

In the drawings,

Figure 1 is a view partly in side elevation and partly in section of acontainer embodying the improvements;

Figure 2 is a similar view of a portion of the body Wall showing anopening formed `in the body wall for the insertion of a tool used forrupturing the metal and forming a free end in the tearing strip on whicha key may be placed for removing the tearing strip.

Figure 3 is a view similar to Figure 2 but showing the metal of the bodywall ruptured and the freed end of the tearing strip lifted preparatoryto the attachment of a key thereto.

Figure 4 is a view in `side elevation of a key which may be used forrupturing the `,metal and lifting the freed end of the tearing ,istripand also for removing the tearing strip. j

The container is preferably made` of sheet metal and the body wall isformed from a blank the edges of which are joined in a'. l`side seam.The body wall is indicated at I in thedrawings and the side seam isindicated at 2. shown, the side seam is of the usual'lock or' lap type,although it will be understood that the invention is not limited to thecharacter of the side seam and thi-s side seam may be a lap seamthroughout. l

The body wall is preferably beaded inwardly,

1 olaiin. (Cl. zent-545V as indicated at 3, and disposed within `theconminer Sa collar 4 which contacts withthe bead 3 at the lowermendthereof."` Attachedwto the cody wall"isaln`,endciosure 5 which issecured tcf` "th"body wall by a double "seam 6. These parts are "all" ofthe usual construction andfurth'er descriptinfiofthe container as `awhole"` is not thought necessary(` o w i The b "nkwhich forrnsthe bodyof thecnf tainerjis scored along parallellines 1, "I; Thesescrlines"preferably extendirorn `one end of the blank to the other andin the finished can completely encircle the body. The "body" wall isalso scored `along *th`e` line` 8 which extends from` onegscoreline tothe other.` Thebmody wall is "further," scored as indicated `at,9. Thisscore lin`e"9 is circular and sets ofi a portion of the body wallwhiciirriay be readily ruptured by pressure applied to the outer face of thecan body so as to provide a hole through the body wall when it isdesired to open thecontainer.

When the body wall is ruptured along the score line 9 an opening I0 isformed. The score line 8 is curved preferably about the center of theopening I0 and, as noted, extends all the Way from one score line 1 tothe other score line 1.

This score line 8 sets oi the end of the tearing of the key is aprojecting member I3 which is preferably tapered toward its free end.When it is desired to open the container this projecting portion of thekey is pressed against the center of the scored portion 9 and the metalruptured along the score line 3. `This will form the hole ID. The key isthen inserted in the hole and, since the projection I3 thereof is of alength substantially equal to the distance between the score line 9 andthe score line 8, the extreme end I4 of said projection will lie closeto the score line 8 but at theleft of the same as viewed in Figure 1. Arotation of the key will bring pressure to bear on the inside of thebody wall ad jacent the score line 8 and this will rupture the metalalong the score line 8 and also to a short distancealong the score line1, thus forming the freed end of the tearing strip. The key is thenremoved and the slot I5 in the shank of the key is placed over the freedend of the tearing strip and,` by rotating the key in the usual way, thetearingstrip will be rolled onto the key and will be completely removedthus releasing the upper portion of the container from the lower portionthereof.

The body wall may also be scored along the line I6, in which case thetearing strip Will be released from the body wall at this score line andthere will be left between the score line 8 and the score line I6 aportion of the body Wall which ywill serve as a hinge, permitting theupper end portion of the container to be turned to open position. and`aga-im brought back". to ai closed position. When-'the body'wall isscored alongf-the line I6 the score lines 1, 'I may terminate at thescore lines 8 and I6, as it is not desirable tot' rupture the metalbetween thesescoreJineswhem.

a hinge portion is left.

The collar is provided wthvavbeadi: IJwhiciii-is'- curved inwardly fromtheffb'od'y wall, thus proa viding a space I8.
